BARREL-PUMP.

SPECIFICATION forming part of Letters Patent No. 263,384, dated August 29, 1882.

Application flied June 13.1882. (No model.) A

inga part of this specification, and to the let-' ters and figures ot' reference marked thereon.

Figure 1 ot' the drawings is a vertical section ot' my invention, and Fig. 2 a horizontal cross-section taken on line y y o f Fig. I.

The present invention has for its object to provide a simple, cheap, effective, and practically-operating pump, that can be readily and securely attached to an oil-barrel or other vessel containing liquids, and that will throw a continuons stream by means of a single piston, andbe free ot' any leakage or waste of oil around the piston. These objectsI attain by the construction, substantially as shown in the drawings, hereinafter described and claimed.

In the accompanying drawings, A represents the outer cylindrical casing ofthe pump, having a central cylinder, B, of less height than the casing` and open at both ends, said cylinder containing a piston, O, provided at its upper end with a suitable handle, a, for actuating it. Tile upper end of the cylinder B is made slightly flaring, as shown at b, and extends above the top of the casing A. This casing has a metal top, D, ot' substantially the form shown, so as to admit the passage of air between it and the upper end of the piston (l, said air passing in its course between the piston and cylinder, and also down into a dripchamber, E, extending the entire length of the cylinder. By this construction the oil or other liquid which is being pumped, and which escapes through the packing into the cylinder B, flows upward through the same and over the top, down into the drip-chamberEand out the escape= opening c, through the casing A, back into the vessel or barrel.

It will thus be seen that there is no waste or loss of oil or other liquid which passes up into the cylinder around the piston, as would be the case when the leather packing d wears away.

The leather packing d is secured to the lower end of the piston O by the metal disk h and screw i. y

A rubber packing, 7c, is interposed between the lnetal disk h and leather packing, so as to equalize the suction and overcome any inequalities or uneveness in the cylinder, the leather turning down over said, rubber, thus making it easy to work and preventing the tightening ofthe leather, as it would when the leather is turned upward on account of the swelling ot' the wood.

The continuons motion of the piston G will cause the liquid to raise the valve e and iiow up into the casing A and through the .tubes F, where it will force the valves g oli" their seats and pass in and around the chamber G, and thence out through the pipe H.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a pump t'or barrels and other vessels, the casing A, having central cylinder, B, and the plunger or piston C, in combination with the chamber Gr and valves g and metal top D,

said top and the cylinder B being open at their upper'ends to form a space around the plunger or piston, substantially as and for the purpose set forth.

2. The combination, with the easing A, passages or tubes F, and chamber G, of the airvent and drip-chamber E, central cylinder, B, plunger C, and the several valves, substantially as and for the purpose set forth.

In 'testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
